Specifically, it is a low-molecular-weight polyphenylene ether that is excellent in heat resistance, electrical characteristics, various solvents, and solubility in reagents, and has good miscibility and reactivity with other components. Furthermore, it relates to a method for efficiently producing the low molecular weight polyphenylene ether, and a low molecular weight polyphenylene ether obtained by this method. [Prior technology] Polyphenylene ether has excellent processability and productivity. It can be used to produce products and components of the desired shape through molding methods such as melt injection molding and melt extrusion molding. Therefore, it is widely used as electrical, Electronic field, automotive field, various other industrial material fields, food packaging field products, components for materials. Many methods of manufacturing polyphenylene ether have been proposed, including Japanese Patent Publication No. 3 6-1 8692, US Patent No. 3 3 06 87 5, and 3 344 1 16 and 3432466. The polyphenylene ethers obtained by these known methods and used in the above applications are high molecular weight polymers having a reduced viscosity of 0.3 dl / g or more. However, recently, polyphenylene ethers of extremely low molecular weight are expected to be more effectively used for electronic material applications such as printed circuit boards than ordinary high molecular weight polyphenylene ethers. In recent years, with the high integration of electronic materials such as printed circuit boards, the conductor loss of the wiring itself has been enlarged by close-ups, and the loss has been released in a thermal form. Therefore, excellent low dielectric constant characteristics and high heat resistance are required for printed circuit board materials. In addition, -6-(2) In the process of manufacturing a printed circuit board, it is usually dissolved in a solvent, functionalized by a modification reaction, and then subjected to a reaction such as hardening. Therefore, it is necessary to have excellent solubility in the solvent and reactivity with other components. Low-molecular-weight polyphenylene ethers are disclosed in JP-A No. 5 0-6 5 2 0, JP-A No. 62-39628, and US Patent No. 6211327, etc., and the low-molecular-weight polyphenylene ether obtained by any method is also heat resistant. And electrical characteristics cannot be called sufficient. In Japanese Patent Publication No. 5-60-6202, it is disclosed in a mixed solvent of aromatic hydrocarbons such as benzene, toluene and xylene, and aliphatic hydrocarbons such as n-hexane, isohexane, and n-heptane. Method for making polyphenylene ether. However, the obtained low-molecular-weight polyphenylene ether cannot be said to be sufficient in terms of heat resistance and electrical characteristics. Moreover, as is clear from the examples, the obtained low-molecular-weight polyphenylene ether has a low viscosity in a low-molecular weight region having a viscosity of 0.2 dl / g or less The molecular weight polyphenylene ether has a problem in that productivity decreases due to adhesion to a reaction vessel or the like. When a good solvent for polyphenylene ether is used as a good solvent for polyphenylene ether (aromatic hydrocarbons such as benzene, toluene, xylene, etc. in the above publication), the good solvent has good affinity for the obtained polyphenylene ether. Therefore, not only the low molecular weight is attached to the reactor to reduce the yield, but also the equipment for removing the good solvent from the polyphenylene ether becomes too large, which has the problem that the temperature control of the equipment must be extremely neurotic. Therefore, the reduced viscosity of the low-molecular-weight polyphenylene ether obtained with good efficiency stays at around 0.2 dl / g at best. Japanese Unexamined Patent Publication No. 62-3 9628 is a low-molecular-weight polyphenylene ether having a number average molecular weight of less than 2 800, and shows the use of monofunctional alcohols having 1 to 5 carbon atoms and water as needed. As a method of polymerization solvent. However, the obtained low-molecular-weight polyphenylene ether (3) (3) 583221 was not sufficient in terms of heat resistance and electrical characteristics, and the yield was only 95% (actually less than 90% in the examples). ), And as described in the examples, it has a problem of extremely time-consuming polymerization, and is not an industrially efficient method. In US Patent No. 62 1 1 327, it is disclosed that the catalyst component in the aqueous phase is removed from the polymerization solution of low molecular weight polyphenylene ether, and then the good solvent of polyphenylene ether is directly degassed from the polyphenylene ether solution ( For example, using a degassing extruder, etc.), a method for producing low molecular weight polyphenylene ether. This method is for the production of extremely low molecular weight polyphenylene ether with a reduced viscosity of about 0.1 dl / g or less. Although it is an improved method without any problem of yield, it cannot be said to be sufficient in terms of heat resistance and electrical characteristics. . Moreover, the low-molecular-weight polyphenylene ethers obtained by these methods generally have a granular or nine-shaped form. Since it has large particles, it takes time to dissolve in the solvent, and it causes troubles such as being semi-dissolved and adhering to the wall of the reaction mechanism. [Summary of the invention] < Disclosure of the invention > The present invention aims to provide a low-molecular-weight polyphenylene ether which is excellent in heat resistance and electrical characteristics and excellent in solubility to solvents and the like.

The secondary monoamine compound and the tertiary monoamine compound are respectively used as constituents of the catalyst, and they can be used separately or in combination. Furthermore, it is also preferable to add a surfactant which is known to have an effect of increasing polymerization activity. For example, trioctylmethylammonium chloride is known under the trade names Aliqu at 3 36 and Capri qu at. The amount used is preferably within a range of not more than 0.1 wt% relative to the total amount of the polymerization reaction mixture. In addition to pure oxygen, the oxygen-containing gas in the polymerization of the present invention may be a gas mixed with an inert gas such as oxygen and nitrogen at an arbitrary ratio, and air, and a gas mixed with an inert gas such as air and nitrogen at an arbitrary ratio. The internal pressure in the polymerization reaction is sufficient if it is normal pressure, but if necessary, reduced pressure or pressure may be used. Although the polymerization temperature is not particularly limited, if it is too low, the reaction is difficult to proceed, and if it is too high, the selectivity of the reaction is reduced. Therefore, it is preferably carried out in the range of 0 to 80 ° C, preferably 10 to 70 ° C. There is no particular limitation on the processing method after the polymerization reaction is completed. The catalyst is usually inactivated by adding acids such as hydrochloric acid and acetic acid, or ethylenediaminetetraacetic acid (EDT a -19- (15)) and its salts, or amine triacetate and its salts. There is also no particular limitation on the method of treating known by-products such as dibenzoquinone, which are by-produced by the polymerization of polyphenylene ether. As described above, if the metal ions of the catalyst are in a substantially deactivated state, they can be decolored by simply heating. Also, a method of adding a necessary amount of a reducing agent such as hydroquinone, sodium bisthionite, or the like may be used. Although the temperature of this step is not particularly limited, it is preferable to perform the operation at a temperature of 10 to 100 ° C. Generally, methods for obtaining polyphenylene ether are known to use a lean solvent of polyphenylene ether as a polymerization solvent, a precipitation polymerization method in which polyphenylene ether is precipitated in a particle form as the polymerization progresses, and a good solvent is used as the polymerization solvent, and A solution polymerization method in which polyphenylic acid is dissolved in a solvent, and the low molecular weight polybenzene of the present invention can be obtained by any method. In the case of using a poor solvent of polyphenylene ether as a polymerization solvent and a precipitation polymerization method in which polyphenylene ether is precipitated along with the polymerization, a mixed solvent of two or more alcohols must be used as the lean solvent. The lean solvent is preferably an alcohol having 1 to 10 carbon atoms. More preferably, two or more kinds are selected from methanol, ethanol, propanol, butanol, pentanol, hexanol, and ethylene glycol. The lean solvent is preferably free of water. If there are two or more types, there is no particular limitation on which one is selected. In addition, the ratio of various solvents in the mixed solvent is not particularly limited, and the combination and ratio of polymerization solvents necessary to achieve the method of the present invention can be selected from these solvents, so it can be selected from a very wide range, but it is industrial From the standpoint of consideration, it is to consider the price, the ease of recovery methods, etc., and of course, to some extent. 0 -20- (16) (16) 583221 Surprisingly, if a mixed solvent of two or more alcohols is used , Although the low-molecular-weight polyphenylene ether is a poor solvent, the molecular weight of the obtained low-molecular-weight polyphenylene ether can be controlled by changing its ratio, and it shows that the polymerization activity and A very specific act of yield. In the polymerization solvent, a good solvent can coexist in a range where the low molecular weight polyphenylene ether will not be dissolved. Therefore, it is necessary to pay attention to the meaning of the so-called total exclusion. For example, in the case of reducing a low molecular weight polyphenylene ether having a viscosity of 0.07 dl / g, a small amount of xylene (about 1%) may be contained in a mixed solvent of methanol and n-butanol. If the reduced viscosity of the polyphenylene ether becomes low, the amount of good solvent that can coexist decreases. In the case of reducing a low molecular weight polyphenylene ether having a viscosity of 0.04 dl / g, the allowable amount of co-existing xylene is about 50 ppm. The amount of good solvent varies according to the desired reduced viscosity of the low molecular weight polyphenylene ether, or according to the degree of affinity of the good solvent for the low molecular weight polyphenylene ether, which cannot be said at one glance, and of course varies according to the type of each solvent 〇 On the other hand, in the case of a solution polymerization method using a good solvent of polyphenylene ether as a polymerization solvent, and adding a lean solvent to a solution containing the obtained low molecular weight polyphenylene ether to make low molecular weight polyphenylene ether Precipitation must be performed in the range of -8 0 to + 2 (TC. Good solvents include benzene, toluene, xylene (including the isomers of o-, m-, and p-), ethylbenzene, styrene, etc. Aromatic hydrocarbons, chloroform, dichloromethane, 1,2-dichloroethane, halogenated hydrocarbons such as chlorobenzene, dichlorobenzene, and nitro compounds such as nitrobenzene. The preferred good solvent is toluene. -21-(17) (17) 583221 Some substances which are poor in solvent but classified as good solvents can be exemplified by aliphatic hydrocarbons such as pentane, hexane, heptane, cyclohexane, cycloheptane, ethyl acetate, etc. , Esters such as ethyl formate, ethers such as tetrahydrofuran, diethyl ether, etc. Methylasco, etc. These good solvents can be used alone or in combination of two or more. Moreover, as long as the reaction mixture after polymerization is a solution, a poor solvent containing alcohols, water, etc. may be used. A solution containing low-molecular-weight polyphenylene ether and a solvent is obtained through polymerization. Although the concentration of the low-molecular-weight polyphenylene ether in the solution is not particularly limited, it is preferably 25 to 70% by weight. By adding a poor solvent to the obtained solution, Examples of the precipitated low molecular weight polyphenylene ether • Lean solvents include ethers, ketones or alcohols. Alcohols having 1 to 100 carbon atoms are preferred, and methanol, ethanol, propanol, butanol, and pentanol are more preferred. At least one selected from the group consisting of hexanol and ethylene glycol. It may also contain water. In the method for precipitating low molecular weight polyphenylene ether, there are no particular restrictions on the device and means. It can be listed in a tank of a suitable size with a mixer Method for continuously adding a solution containing a low molecular weight polyphenylene ether and a lean solvent, adding a lean solvent to a tank containing a low molecular weight polyphenylene ether solution, and adding a low molecular weight to a tank containing a lean cereal Various methods such as a method of benzin solution, a method of continuously adding a solution containing a low molecular weight polyphenylene ether and a lean solvent in a tube-type static mixer, and a temperature and a lean solvent containing a low molecular weight polyphenylene ether solution supplied in a precipitation device. Although the temperature is not particularly limited, full attention must be paid to the temperature of the precipitation operation in the precipitation device. In order to obtain the low molecular weight polyphenylene ether of the present invention, the precipitation must be performed within a range of -80 to +20 ° C. If it exceeds 2 ° t -22- (18) 'The low molecular weight polyphenylene ether is attached to the reactor, etc., and the low molecular weight polyphenylene ether cannot be precipitated. Moreover, although low molecular weight polyphenylene ether can be obtained at temperatures below -80 ° C, Lowering to less than -80t requires great energy and is not efficient. Any of the above * methods can obtain a slurry containing low molecular weight polyphenylene and a solvent. The low molecular weight polyphenylene ether of the present invention can be obtained from a slurry Obtained by removing the remaining solvent. The method of removing the solvent includes a method of solid-liquid separation of the slurry, to obtain a wet low-molecular-weight polyphenylene ether, and drying or obtaining a low-molecular-weight polyphenylene ether by direct degassing. The means of solid-liquid separation is not particularly limited. All previously known methods can be used. For example, a filter type centrifugal separator, a centrifugal separator with a scraper blade, a vacuum drum filter, a hopper, etc. can be used. In addition, when a good solvent is used as a polymerization solvent, and the obtained stream is precipitated at a low temperature, the initial filtration temperature must be performed within the temperature range described in the precipitation temperature. Prior to the drying or direct degassing method, the obtained wet low molecular weight polyphenylene ether is preferably washed with a lean solvent of the low molecular weight polyphenylene ether. The washing solvent is preferably at least one selected from methanol, ethanol, propanol, butanol, pentanol, hexanol and ethylene glycol. The method of making water in the washing solvent is preferable. Low-molecular-weight polyphenylene ether can be obtained by drying or directly degassing the obtained wet low-molecular-weight polyphenylene ether. There is no particular limitation on the drying method. All previously known methods can be used. For example, a paddle dryer, a vacuum dryer, a spray dryer, a heating tube dryer, and the like can be used. Especially for inert gas operation. Under this type of drying method, the low molecular weight -23- (19) polyphenylene ether of the present invention is obtained as a powder. The direct degassing method is a method in which the obtained wet polyphenylene ether is heated to remove volatile solvents and the like. This method includes, for example, supplying a wet low-molecular-weight polyphenylene ether to a heated degassing extruder, and cooling and cutting off the low-molecular-weight polyphenylene ether of the present invention discharged from a mold while degassing volatile components. The method of obtaining nine objects is to put a suitable container of wet low molecular weight polyphenylene ether under reduced pressure, remove the solvent, and solidify the low molecular weight polyphenylene ether of the present invention.
